Has an AFL game ever ended 150-77?
Exactly once. On April 16, 1990, Geelong beat Fitzroy 150-77, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 150-77 in league history.
That makes 150-77 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 151-77 has happened 2 times and 150-78 has happened 1 times.
